According to new scientific reports, due to the melting of glacial ice, the rising sea levels have reached the highest point in 6 millennia. A new scientific study published this week in the Proceedings of the National Academy of Sciences magazine shows that the rising sea levels have reached an all-time high - or at least, higher than any human society has ever documented.
The rising sea levels can come from two major forces: thermal expansion (which means the ocean water warms up and therefore expands) and an influx of additional water caused by the melting of ice sheets and glaciers. Due to the recent growing climate changes, it's safe to say that the current rising sea levels the Earth is experiencing are due to the fact that glaciers are melting in the coldest regions of the planet.
A new study called "Sea level and global ice volumes from the Last Glacial Maximum to the Holocene" and published in the Proceedings of the National Academy of Sciences magazine suggests that the ocean been surprisingly static for the past 4,000 years - a fact that changed only around 150 years ago, right about the time that human civilization began to pump greenhouse gases into the atmosphere by burning fossil fuels. Ever since, rising sea levels have reached their highest peaks in centuries, mostly due to the fact that the Earth has warmed and there is less ice and more water.
Regarding the climatic change, lead paper author Kurt Lambeck told the press: "What we see in the tide gauges, we don't see in the past record, so there's something going on today that's wasn't going on before. I think that is clearly the impact of rising temperatures."
Only a few weeks ago, it was reported that 35,000 walruses appeared on the shores of Alaska, as their natural habitats, blocks of ice in the middle of the Antarctic, were no longer frozen - or rather, the remaining frozen ones were too far north for the walruses to swim to. Due to this fact, the mammals took up to the Alaskan beaches.
